Best for Platform teams needing granular, namespace-level Kubernetes cost visibility rather than blended cloud bills. Teams wanting a free, vendor-neutral standard for Kubernetes cost allocation without a commercial product. Engineering-led teams that want transparent, self-serve pricing for cloud cost visibility without a sales cycle. Kubernetes platform teams wanting automated cost optimization rather than just recommendations to act on manually. Mid-to-large enterprises running a formal, multi-cloud FinOps practice across finance and engineering.
